Monday, September 30, How to softwaree the serial number of a program with OllyDbg. Some months ago, I participated in something like a Hpw Competition" to get a job in a CERT. One of the tests consisted of getting the serial key of a simple program.
We are going to work with OllyDbg How to crack trial software using ollydbg. You can download this awesome tool from here: OllyDbg v1. The first thing I usually ollyrbg in these cases is to check if the executable is compressed or not. Some programs pack some of their codes in order to limit tp attempt to statically analyze it. To achieve this purpose we are olllydbg to use PeID. If the file were compressed with UPX for example, the program would advise us about it and we could uncompress it with this tool.
We can see the R. Size Raw Size "" and the V. Size Virtual Size "" are. If some day you detect that the R. Size is "0" and the V. Size is "" for. Now we have the assurance that the file has not been compressed. This is one of the first steps in a static analysis. We are going to make a dynamic analysis with OllyDbg but I want to know if the developer has made an effort in order to try to hide some code.
Notice if the executable is packed then we are not going to be able to read a lot of strings within the file. It is possible I will talk about that in future posts. We have not figured out the serial number Now, we are going to run OllyDbg. It does not need installation, just download it and uncompress it. Now we can see the binary code. We are going to click on the play button in order to run the executable just loaded in our debugger and check the file behaviour.
The program has started and we can see the firsts strings like "Press ENTER to finish" Please, click on the picture to see the entire details. If we reload the file again on OllyDbg, one line of the code draws our attention The program is calling to the "IsDebuggerPresent" API. If we seek this API on Microsoft we can see that "This function allows an application to determine whether or not it is being debugged, so that it can modify its behavior".
Ok, the program is closed when it is open within a sovtware. There are many options to avoid being detected by this technique To achieve this purpose we are going to use the " Hide Debugger 1. It is necessary to restart OllyDbg in order to work with this plugin. If you click on Plugins tab you can see Hide Debugger plugin. We have just installed the plugin to avoid being detected and now, we are going sodtware load and play the executable again.
Now the program requires typing the serial number. If we continue looking for this sentence through the code we can locate the code below. We can figure out that the executable is comparing these strings to each other in order for you to check if hrial have the same value. We can suppose that the string "" is serial number. OllyDbg offers us to copy the value of this line by left clicking on the line we are interested in. In the end, we just need to try paste the value just copied in our program and We have obtained the serial number of our program!!!
This post could be applied to many of the simple programs which have a keygen integrated but it is needed to have more knowledge if you want to crack more complex programs. This post is focus on show you some techniques using OllyDbg. It is only a game to get more reversing engineer skills to How to crack trial software using ollydbg malware.
